Zomwe zimagwiritsidwa ntchito pazida za hardware

Zida zamagetsi nthawi zambiri zimapangidwa ndi chitsulo, mkuwa, ndi labala

Chitsulo: Zida zambiri za hardware zimapangidwa ndi chitsulo

Mkuwa: Zida zina zachiwawa zimagwiritsa ntchito mkuwa ngati zinthu

Mphira: Zida zina zachiwawa zimagwiritsa ntchito mphira ngati zinthu

Ngati mankhwala agawanika, akhoza kufotokozedwa mwachidule ngati magulu awiri akuluakulu a carbon steel ndi alloy steel.

Iwo lagawidwa m'magulu atatu: structural zitsulo, chida chitsulo ndi ntchito zitsulo wapadera.

Malingana ndi khalidweli, mitundu itatu yazitsulo wamba, zitsulo zamtengo wapatali zimagawidwa.

carbon steel

The mpweya zili mpweya zitsulo pansi 1.5%, zili mpweya zitsulo amatchedwa "0.25% otsika mpweya zitsulo, 0,25% mpweya zitsulo zosakwana kapena wofanana 0,6% pakati pa mpweya zitsulo, mpweya zitsulo ndi mkulu mpweya zitsulo ndi kuposa 0.6%.

Chifukwa phosphorous ndi sulfure akhoza kuonjezera brittleness zitsulo pa kutentha otsika kapena kutentha kwambiri, zili phosphorous ndi sulfure mu zitsulo ayenera kutanthauziridwa pamene khalidwe la gulu.Chitsulo wamba, chomwe chili ndi zosakwana 0.045% sulfure zosakwana 0.055%.Mkulu khalidwe zitsulo, phosphorous zili zosakwana 0,04%, sulfure zili zosakwana 0.045%.The sulfure zili chida zitsulo, P = 0,04% motero.Muzitsulo zapamwamba kwambiri, phosphorous ndi sulfure zofunikira zinali zosakwana 0.03%.

Chitsulo cha carbon structural chimagwiritsidwa ntchito kwambiri popanga zida zosiyanasiyana zaumisiri (monga mlatho, zombo ndi zida zomangira) ndi zida zamakina, monga magiya, mitsinje ndi ndodo zolumikizira, ndi zina zambiri, zomwe nthawi zambiri zimakhala za chitsulo chochepa cha carbon ndi mpweya wapakatikati.

Chitsulo cha zida za kaboni ndicho chilankhulo chachikulu chopangira zida zosiyanasiyana, zida zoyezera, zida zogwira ntchito ndi zida za Hardware, zomwe nthawi zambiri zimakhala zachitsulo cha carbon.Mpweya chida zitsulo zitsulo ndi "T", monga T7 anati mpweya mpweya aloyi chida zitsulo 0,7%.Chitsulo chapamwamba cha carbon chida chimayimiridwa ndi "A" pambuyo pa chiwerengero, monga "T7 A".

Kalasi ndi chitsulo.Chitsulo chamtunduwu chimaperekedwa ngati chitsimikizo cha zinthu zamakina.Ndi chiwerengero cha magiredi 1-7, kuchuluka kwa chitsulo kumakhala kokulirapo, kukulitsa mphamvu zokolola komanso kulimba kwamphamvu, koma kukulirakulira.

Gulu B lachitsulo, chitsulo chamtunduwu chimaperekedwa ndi mankhwala.Ndi chiwerengero cha 1-7 magiredi, kuchuluka kwa B chitsulo kumakhala kokwera kwambiri kwa carbon.

Chitsulo chachitsulo

Pofuna kupititsa patsogolo makina, katundu wa ndondomeko, thupi ndi mankhwala azitsulo, zinthu zina zowonjezera zimawonjezeredwa kuzitsulo panthawi yosungunuka, yomwe imatchedwa chitsulo cha alloy.The pafupifupi mpweya zili zoposa 1% aloyi chida zitsulo pamene zili mpweya si chizindikiro, pafupifupi mpweya zili zosakwana 1%, ndi ochepa anati.

Chiwerengero chonse cha zinthu alloying zitsulo amatchedwa <5% otsika aloyi zitsulo, 5% zosakwana okwana zosakwana 10% aloyi zinthu zotchedwa zitsulo aloyi, aloyi zinthu amatchedwa 10%, okwana kuchuluka kwa mkulu aloyi zitsulo.

Chitsulo cha aloyi chikhoza kupeza zinthu zamakina zomwe zimakhala zovuta kukwaniritsa muzitsulo za carbon.

Chromium: onjezerani kuuma kwachitsulo ndikuwongolera kukana kovala ndikuwonjezera kuuma.

Vanadium: imathandizira kwambiri kulimbitsa kulimba, kukana kuvala komanso kulimba kwachitsulo, makamaka pakuwongolera kulimba kwachitsulo.

Mo: imatha kukulitsa kulimba ndi kukhazikika kwachitsulo, kuyeretsa njere ndikuwongolera kusagwirizana kwa carbides, motero kumapangitsa mphamvu ndi kulimba kwachitsulo.

Zitsulo zomwe zimagwiritsidwa ntchito pazida za hardware

Chifukwa cha zida zapadera zamakina a alloy chida chitsulo, chitsulo cha alloy chida nthawi zambiri chimagwiritsidwa ntchito pakati ndi zida zapamwamba za hardware.Amagwiritsidwa ntchito makamaka ku malo okonzera nthunzi, fakitale yamagalimoto, malo opangira magetsi ndi mabizinesi akumafakitale ndi migodi omwe ali ndi zida zapamwamba zogwiritsira ntchito zida komanso zofunikira zapamwamba za zida.

Chitsulo cha zida za kaboni nthawi zambiri chimagwiritsidwa ntchito pazida zotsika, zomwe zimakhala ndi mwayi wamtengo wotsika.Ndizoyenera makamaka kwa ogwiritsa ntchito apakhomo omwe ali ndi chiwongola dzanja chochepa komanso osafuna zida zambiri.
